Lost postgreSQL password in Windows installation [duplicate]

Question

This question already has an answer here:

• Forgotten PostgreSQL Windows password 3 answers

I have postgresql 9.2 installed on a windows XP machine. I have lost the postgres password.

I looked at answers given to a similar question asked 6 months ago. The answer given there required the editing of a file pg_hba.conf however I cannot find that file anywhere. Windows search doesn't find it.

I have tried uninstalling the postgreSQL installation but that seems to leave behind the password and security settings as on installing again the step to set the postgres password is missed out.

Help please?
